The Wallabies are likely to start Mike Harris at fullback for their upcoming Rugby Championship Test against Argentina.

Harris is set to become the Wallabies’ fifth fullback in 10 Tests this season. With Berrick Barnes out with a punctured lung, the Reds utility back was running in the position during training on Tuesday.

Anthony Faingaa or Ben Tapuai are set to replace the injured Adam Ashley-Cooper (concussion) at outside centre.

Wing Digby Ioane and flank Scott Higginbotham missed training, but are both expected to recover in time for the final round of the Rugby Championship this weekend.
